Product Description

Product Description
This inertial navigation system integrates precision laser gyroscopes and quartz accelerometers with a modern strapdown architecture to deliver accurate navigation and attitude information. Supported by real-time navigation algorithms, the system offers flexible operational modes including hybrid inertial-GNSS and standalone inertial navigation. It continuously outputs essential navigation parameters such as heading, roll, pitch, location, and velocity for maritime applications requiring high reliability and accuracy.

Key Advantages

High Stability Heading Output based on precision laser gyros
Accurate Motion Attitude including roll & pitch measurements
Hybrid GNSS + INS Support for reliable positioning under signal loss
Fast Initialization & Autonomous Navigation for different maritime scenarios
Robust Strapdown Architecture improving performance and system reliability

Application Fields

Surface Vessels (OPVs / Patrol Boats / Survey Vessels)
High-Speed Craft / Ferries
Maritime Navigation & Positioning Systems
Marine Survey & Mapping Platforms
Autonomous Marine Vehicles (USV / AUV)
